Abstract

Foreliggende oppfinnelse angår en aktuator for lineær bevegelse, omfat- tende en motor (5) forsynt med en roterbar motoraksel (4), en bevegelsesaksel (6), en gjenget overføring (7, 8) mellom motorakselen og bevegelsesakselen, en bæreramme (9), en styringsstøtte (10, 11) mellom bærerammen (9) og bevegel- sesakselen (6) for å forandre motorakselens roterende bevegelse til en lineær bevegelse for bevegelsesakselen, og videre en klarings-fjerningsanordning (12) for å fjerne klaring i aksial retning. Den gjengede overføringen (7, 8) mellom mo- torakselen (4) og bevegelsesakselen (6) omfatter en innvendig gjenge (7) i motor- akselen (4) og en utvendig gjenge (8) på bevegelsesakselen (6). l samsvar med oppfinnelsen omfatter aktuatoren for lineær bevegelse en anordning (12 eller 30) for å fjerne vertikale, horisontale og rotasjonsmessige klaringer.The present invention relates to an actuator for linear motion, comprising a motor (5) provided with a rotatable motor shaft (4), a movement shaft (6), a threaded transmission (7, 8) between the motor shaft and the motion shaft, a support frame (9). , a guide support (10, 11) between the support frame (9) and the motion shaft (6) to change the rotary motion of the motor shaft to a linear motion of the motion shaft, and further, a clearance removal device (12) to remove clearance in the axial direction. The threaded transmission (7, 8) between the motor shaft (4) and the motion shaft (6) comprises an internal thread (7) of the motor shaft (4) and an external thread (8) of the motion shaft (6). In accordance with the invention, the linear motion actuator comprises a device (12 or 30) for removing vertical, horizontal and rotational clearances.
